class Sign(mode: str = MetricAggregationMode.per_segment, **kwargs)[source]

Bases: etna.metrics.base.Metric

Sign error metric with multi-segment computation support.

\[Sign(y\_true, y\_pred) = \frac{1}{n}\cdot\sum_{i=0}^{n - 1}{sign(y\_true_i - y\_pred_i)}\]

Notes

You can read more about logic of multi-segment metrics in Metric docs.
